' INVESTORS CALVIN V. REAMS AND JAMES B. HOPKINS, OF SUISN, CALIFORNIA, ASSIGNORS .0F ONE-FOURTH TO JOSEPH B. CHAIDBOUR-NE AND ONE-FOURTH TO EDWIN J. SPARKS,

BOTH 0F SUISUN, CALIFORNA.

Application filed August 21, 1915.

To all whom t may concern Be it known that we, CALVIN V. REAMs and JAMES' B. HOPKINS, citizens of the United. States, residing at Suisun, in the county of Solano and State of California, have invented new and useful Improvements in Wrenches, of'which the following is a specification.

This invention relates to a pipe and nut wrench. v v

One of the objects of the present invention is to provide a simple, substantial, cheaply manufactured wrench adapted for use both as a pipe and a nut wrench, and which is so constructed that it may be operated ratchetv fashion when used.

- Further objects will hereinafter appear.

AThe invention consists of the parts and the construction and combination of parts as hereinafter more fully described, having reference to the accompanying drawings, in Which- .Figure 1 is aside elevation of the wrench, partly broken away. Fig. 2 is `a plan View of same, partly in section. Fig. 8 is a cross section on line 3-3 of Fig. 1.

Referring indetail to the drawings, A indicates the main stationary` jaw of the wrench, 2 the shankand 3 the handle; the shank and handle being preferably thick in construction to produce' rigidity, but cored out at the sides, as indicated by the crosssections at 4 and 5, to eliminate weight as much as possible.

Formed integrally with the shank is a guide member 6 which is provided with a longitudinally disposed, rectangular-shaped slot 7through which the threaded shank 8 of the movable jaw 9 extends. Theguide member is also slotted crosswise to permit the insertion of a nut 10, of the usual construction, which, when turned from the exterior, will move the threaded shank 8 in one direction or the other to adjust the position of the movable jaw 9.

Slidably mounted and surrounding the main shank 2 is a fork-shaped carriage 11 which is secured to the inner end of shank 8 i b v a screw 12, or other similar means, and pivotally mounted, `as at 13, in the opposite end of the carriage' 11 is the movable jaw 9. Formed on the 'upper side of the main jaw A is a pair of upwardly extending Specification of Letters Patent WRENCH.

guide lugs 14 between which the movable jaw extends. These lugs are provided for the purpose of guiding the movable jaw 9 when it swings about its pivot 13 and are also provided for the purpose of bracing same' against side movement or lateral strains, thus relieving the pivot 13 and the .connected carriage 11 I:trom being twisted or subjected to other strains than a longitudinal pull.

Formed on the inner end of the movable jaw 9,- on the opposite side of pivot 13, is an extension or lug 15, and formed on the inner end of the shank 8, in line with the lug 15 and just below same, is a supporting lug 16, between which a'nd lug 15 is interposed coil spring 17, said spring being held in position not only by the side walls of the carriage 11 but also by means of cen- 20, where the wrench is to be used both as apipe and nut wrench, vor may be perfectly smooth and used as a nut wrench only.

In operation, the position of the movable jaw 9, with relation to the stationary jaw A, is secured by turning the nut 1() in one direction or the other. This will cause the threaded shank 8, with vconnected carriage 11 and jaw 9, to.slide longitudinally upon the main shank, thus securing the desired adjustment or positioir of one jaw with relation to the other or to the pipe or nut to be turned. Weight isI then applied, -by meansl of the hand,'in the direction of arrow a. 'pipe or nut and turn same in the direction indicated. Return movement in* the direction opposite to arrow a will permit the wrench to ratchet as the jaw 9 may' move about pivot 13 against the tension of spring 17 into the dotted' line position indicated at 22.- A ratchet action is thus produced on This causes the jaws to grip the I roo i the vreturn movement which isy particularly desirable when tighteningv or unserew'ing nuts; or like members. 'i

A. wrench constructed as here shown is rigid in construction, but at the Sametime is comparatively light, as both'` the main shank and the handle are cored out on the sides, as indicated at 2i. This is also true threaded shank pivotally secured to the rear of the movable jaw with its connected threaded shank 8; The provision of the upwardly extending guide lugs 14 materially increase the strength and rigidity of the movable parts as they take up all side strain vor lateral movement imparted tothe movable jaw, with connected carriage 1l and l shank 8.

The wrench as a whole 'may be quickly adjusted and operated, as it works ratchetfashion and is adjusted by the single mech-A anism, such as the nut 10.

The materials and finish. of the several parts of the device are such as the experience and judgment of the manufacturer may d-ictate. n

We wish it understood that' various changes in form, proportions and minor details of construction may be resorted t0' within4 the scope ofthe appended claims, and that we do not wish to limit ourselves` to the specific design and construction.`

.Having thus described our invention, what we claim and desire to secure by Let ters Patent is-' l. In a wrench, a shank provided with a rigid jaw, a carriage on the shank, a

end of the carriage, a movable jaw having a shank which latter is pivoted between its ends to the front end ofthe carriage, said threaded shank having -a lower forwardly extending lug and said shank of the movable jaw having an upper rearwardly extending lug, a coil spring in the cut-out of the carriage engaged at its ends with said lugs, and means on the main sha'nk engaged with the threaded shank toactuate the latter', said carriage and the inner ends of the threaded shank and movablejaw and the lugs forming a housing which conn-` pletely incloses the spring.

` 2. lIn a wrench, a shankprovided with a rigid jaw,` a carriage on the shank, a threaded shank pivotally secured to the rear end of the carriage, a movable jaw having i va shank which latter is pivoted between its ends to the front end of the carriage, said l threaded shankhaving a`l'owerforwardly extending lug and said shank of the vInovable jaw having an upper rearwardly eX- tending lug, a coil spring engaged at its ends with said lugs, a lug extending from the inner side of the shank oi' the movable jaw and engageablewiththe main shank to relieve the pivot of said shank of the movable jaw and located adjacent .the pivot of the shank of the movable jaw, and means engaged with the threaded shank t'o actuate same..

3. In a wrench, a shank having a rigid jaw, a carriage ,slotted on one side and mounted on said shank, a threaded shank having one end projecting into theslot oit' the carriage from one 'end of saidslotand pivotally secured to the carriage, a mov-` able jaw havinga shank which latter at its inner end extends into the other end of .the carriage slot and is pivoted to the carriage, an upper lugon the last. named shank, a lower lug on the threaded shank, a coil spring in the-slot engaged at its ends with'
